Bléneau is a commune in the Yonne department in Bourgogne-Franche-Comté in north-central France.
Blénau, the administrative centre of its natural area, is a commune of 1,492 inhabitants (in 2012) in the Puisaye area. The commune is on the site of an ancient route that crossed the Loing. The commune covers 3941 hectares and has forests, ponds and grazing lands on its territory. Bléneau is situated at 150km from Paris, 56km from Auxerre and 29km from Gien.
Like the rest of Yonne, Bléneau is on the geological region of the Paris Bassin, but the natural area of Puisaye is characterized by the presence of Puisaye sand and the presence of groundwater that permeate the soil. Bléneau thus presents many wetland habitats and meadows on its territory.
There is a Natural site of importance (Natura 2000) on the territory of the commune, at the limit of the neighbouring commune of Saint-Privé. That natural site is composed of oligotrophic ponds where littorella plants grow and their adjacent damp meadows. The protected site presents a complexe ensemble of green landscapes, damp or dry, in every stage of vegetale colonisation.
Humane presence on the territory is present since Palaeolithic, and many silex tools were found, notably by André Huchet on a site near the limit of Bléneau and Saint-Privé. More than 2000 silex tools were collected on a territory of less than 25 hectares.
The commune is first mentionned in the 6th century in an official text called Statuts de Saint-Aunaire évèque d’Auxerre de 572 à 603 which listed the 38 parishes of Puisaye. The commune was listed under the name Blanoilus and is considered an important community of the area. The origin of the name Bléneau is unclear, and there are hypothesis of a gaulish or celtic origin.
